Spectrometer LMICP-A201 is intended for measuring major, minor, and trace elements in a variety of samples. It has an advanced optical design that includes a fully illuminated holographic grating with special interference correction and a monochromator with a diameter of 1000 mm. The instrument has a wavelength range of 195 to 800 nm and a testing speed of 5 to 8 elements per minute, making it suitable for sample content ranging from 0.01 ppm to several thousand ppm units. Incorporated with three concentric quartz torch rubs of ED 35 mm and a double-pass Scott spray chamber, the device is ideal for wide sample analysis.
